# Plan: Add FastAPI to the Project

## Goal
Add FastAPI as the web framework with a minimal health check endpoint.

## Changes

### 1. Dependencies
- Add `fastapi` and `uvicorn[standard]` to `pyproject.toml` under `[project.dependencies]`
- Install dependencies into the virtual environment

### 2. Application Entry Point
- Create `main.py` with a FastAPI app instance
- Add a health check endpoint (`GET /`) that returns `{"status": "ok"}`

## Verification
- `pytest tests/` — all tests pass
- `uvicorn main:app --reload` — server starts and health endpoint responds
